Parlec ER16-0343 ER16 Collet 0.343 Inches

Product Description

The PARLEC ER16-0343 is an ER16 series collet designed for precision workholding in CNC machining centers, milling machines, and other rotating spindle applications. It accepts tool shanks up to 0.343 inches and has a minimum collet capacity of 0.304 inches, giving machinists a controlled clamping range for consistent tool retention. The overall length measures 1.082 inches and the overall diameter is 0.669 inches. This collet is installed by machinists and tooling technicians who require accurate, repeatable tool holding in high-speed cutting operations.

The ER16-0343 is suited for use in ER16-compatible collet chucks found in CNC machining centers, manual mills, lathes with live tooling, and router spindles. It is a standard ER16 form-factor collet, making it a common consumable in job shops and production environments where a range of tool shank sizes is handled regularly.

Compatibility

Designed for use with ER16 collet chuck bodies that accept the standard ER16 collet form factor. Verify chuck series and collet bore size before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Before changing collets, power down the spindle completely and confirm the machine is in a safe, locked-out state. Seat the collet fully into the nut before threading onto the chuck body, and use a calibrated torque wrench with the appropriate spanner to avoid overtightening. Inspect the collet bore and seating surfaces for debris or wear before each use.
